Molecules of the title compound, C10H12N4O5, are linked to generate sheets which lie in the ab plane at z = 0, 1/2, 1 etc. by means of N-H...O intermolecular hydrogen bonds [N...O 2.844(2)-3.232(2) Angstrom] and inversion centres. The 5-diacetamido group is oriented almost normal to the uracil plane [interplanar angle 87.1(1)degrees] and the 6-acetamido group is held almost planar with the uracil plane [interplanar angle 7.1(1)degrees] via an intramolecular N-H...O hydrogen bond [N...O 2.624(2) Angstrom].
